the M may or may not be attached, I think the following regex should match all possible values

Thanks, this is great to know. Good suggestion to combine the to patterns to one. I have only
one comment:
Any reason why we should use * instead of ? for the optional characters that will (as I understand
it) occur maximum once, specifically : and M?

> getDatabaseProductVersion and getDriverVersion() report only the four digit Derby version
number and not the svn build number.   It would be useful to return  the full version including
the build number  as sysinfo does: e.g. "10.1.2.4 - (392472)", That way it will be clear from
application logs that collect this information exactly what revision level they are running
if they are using rolled up fixes on the maintenance branch between releases.
> There may be risk in doing this however if applications are parsing the version information,
but hopefully they will use getDatabaseMajorVersion() , getDatbaseMinorVersion, getDriverMajorVersion,
and getDriverMinorVersion for such proccessing.
